Ayuh,........... the Same........<br />
Ayuh,.......... In 96, you Might have Vortec heads(8 manifold bolts)...... Probably Not(12 manifold bolts).........<br />You Must have a 4bbl. manifold, or the swap is Useless...........<br />As to Which manifold,.. Count the Bolts....<br />
Probably............<br /><br />BTW,... Welcome to the iboats forums......
<br /><br />Minneapolis is the home port, so I might be able to get away with the aluminum manifold. That sure does open up a few hundred possibilities!<br /><br />Would that also mean that I could utilize a non-marine carb set up? If so, what would you think the max would be, 750?
No,...Nope,...Nada,....No Way..............<br /><br />A Marine Carb is Vented into the venturies, with J-tubes..... A Must Have Item.......<br />
Way Tooo Big...... You'll be Loosing the Vacuum Signals to the carb.......<br />A 350cid can Only move about 565CFMs,@ 5000RPMs........In a Perfect, Well Breathing motor......<br />Anything over a 650CFM is Tooo Much......<br />
Ya,... Well,.. Don't get Carried Away......<br />There's No Sense in trying to add alot of volume to the Intake,<br />Because in this application, the Exhaust is a Major Choke Point........<br />Thru-Hulls will Help, But, to build any Real Horsepower, You Start with Headers.........
Personally, I've fallen in Love with the Merc/Weber/Carter/Eldebrock AFB Carb........<br />My 4.3LX had 1 on it when I got it... Ran Way Rich at idle, Trolling Speeds..... Ya, I'm a Troller....<br />I Finally Found the Carter Strip Kit, part # 10-201.. Handfuls of Needles, Jets,+ Springs...<br />Now, My Plugs run a Beautiful "Coffee & Cream" Brown..... No More Raw Gas Smell,+ Black Plugs........<br /><br />
Ayuh,....... If you want a Rochester........<br />And,<br />"In 96, you Might have Vortec heads(8 manifold bolts)...... Probably Not(12 manifold bolts).........<br />You Must have a 4bbl. manifold, or the swap is Useless...........<br />As to Which manifold,.. Count the Bolts...."<br /><br />The AFB Carbs are a Square bore mount....
That's a Different Chapter, in a Different Book..........
, from the info I found, you can't tell for sure until you look inside . I wouldn't let that change the decission going to 4brl anyway. I'd wait on making any prop change until you have dialed the new carb in, and see where you are at with WOT. <br /><br />FWIW, I'm doing the same mod to my '97 5.7L, and using the edelbrock performer and plan on the 600/625 weber/edelbrock/carter. I was too chicken to go to the high rise used by the 350 mag engines
